f5 ning machine.

' Inthe ordinary rayonspinning machine construction, the funnel bracket comprises a pivoted structure mountedv on the traverse mechanism and movable from a substantially vertical inoperative position to a substantially horizontal operative position, the funnel being carried by the outer end of this pivoted structure. The funnel itself is slip-jointed in the outer end of the structure and the weight of the funnel and the weight of the structure itself is depended upon to maintain the structure in its operative position during reciprocation. When, however, the spinning machine is operated at high speeds, there is a tendency of the arm constituting the bracket to swing about its pivot during the reversal of direction of operation and there is, furthermore, a tendency of the funnel to slip in its mounting on the bracket, with the result that an imperfect cake is formed.

Important objects of the present invention are to provide a means for maintaining the arm or bracket in its horizontal operative position which will be so constructed that the arm may be readily moved to its inoperative position without the manipulation of any part other than the bracket itself, and to provide a means which will securely maintain the funnel in its proper position with relation to the arm and will, at the same time, permit ready removal of the funnel, which must be accomplished in order that the bracket may be moved to its inoperative position.

'I'hese and other objects I attain by the construction shown in the accompanying drawings wherein, for the purpose of illustration, I have shown a preferred embodiment of my invention and wherein:

Fig. 1 is a sectional view through a portion or the spinning machine embodying a funnel bracket construction in accordance with my invention, the bracket being shown in solid lines in its operative position with the funnel therein, and in dotted lines in its elevated position with the funnel removed;

Fig. 2 is a sectional view through the bracket, taken on line 2 2 of Fig. 3;

Fig. 3 is a plan view of the bracket with the funnel removed;

Fig. 4 is a longitudinal sectional view through the funnel bracket; and

Fig. 5 is an enlarged plan view of the funnel mounting proper.

934, Serial No. 733,519

(Cl. 11S- 49) Referring now more particularly to the drawings, the numeral I0 generally designates a traverse rod of a rayon spinning machine upon which, in accordance with my invention, I mount a support il having a recess I2 formed therein 5 which is open at the top and one end of the support. The opposed walls of this recess, adjacent the end opening thereof, flare downwardly and outwardly, as more clearly seen at I3 in Fig. 2. A bracket arm Iii is pivoted within said support, as at I5, and is provided with the usual adjusting screw IS, by means of which the position of the outer end of the arm when in its horizontal operative position may be accurately determined. Since the arm itself and the support I I are preferably formed of some acid-resistant composition, such as bakelite or hard rubber, a monel metal insert Il is provided for abutment by the adjusting screw I6.

This screw, in accordance with my invention, provides an anchorage for a spring latch I8, which latch comprises a rubber covered spring having a iiat central portion located within a transverse groove I9 formed in the arm. This iiat central portion is provided with terminal portions 20 which extend downwardly and converge upon one another, having the outer faces of their tips spaced from one another a distance slightly less than the distance between the upper ends of the flared wall portions I3 so that when the arm is moved downwardly it may enter between the upper ends of these walls, and the rounded corners of the upper ends of the walls indicated at 2| may act to wedge the spring inwardly so that the v terminals may pass and enter the recess I I. I-Iaving entered the recess II, these terminals bear against the downwardly flaring wall portions I3 and constantly tend to wedge the arm downwardly so that the adjusting screw i6 is always maintained in proper contact with the abutment I1.

The outer end of the arm` has threaded therethrough a sleeve 22 constituting a vertically adjustable support for the funnel 23, this adjustment permitting accurate vertical positioning of the lower or discharge end of the funnel. Mounted in the sleeve is a funnel bushing 24, this bushing having a sliding iit in sleeve 22, and having the funnel secured therein by sulphur, or some similar expedient as is usual. In order to prevent vertical movement between the sleeve and bushing, and at the same time permit the funnel to be rapidly removed, I provide a quick detachable coupling between these elements, such coupling comprising a cam projection 25 upon the 55 head of bushing 24 co-acting with an undercut fil and similar cam surface 26 formed upon the head of sleeve 22. The bushing is provided with wing projections 2l upon its head so that it may be readily rotated to engage or disengage the coupling, The head of sleeve 22 is formed as a nut so that this sleeve may be readily rotated and a lock nut 28 is provided for securing this sleeve in its adjusted positions.

Since the construction is capable of considerable modification without in any manner departing from the spirit of the invention, I do not w'ish to be understood as limiting myself thereto except as hereinafter claimed.

I claim:

1. In rayon spinning apparatus, a reciprocable support, a funnel bracket pivoted thereto for movement from a substantially vertical inoperative position to a substantially horizontal operative position, a spring latch maintaining said bracket in its operative position and releasable by application of upward pressure on the bracket, and a funnel carried by the bracket.

2. In rayon spinning apparatus, a reciprocable support, a funnel bracket pivoted thereto for movement from a substantially vertical inoperative position to a substantially horizontal operative position, a spring latch maintaining said bracket in its operative position and releasable by application of upward pressure on the bracket, and a funnel carried by Athe bracket, said support embodying confronting downwardly divergent walls, said spring latch having Wedging engagement against said Walls in the operative position of the bracket.

3. In rayon spinning apparatus, a reciprocable support, a funnel bracket pivoted thereto for movement from a, substantially vertical inoperative position to a substantially horizontal opera.- tive position, a spring latch maintaining said bracket in its operative position and releasable by application of upward pressure on the bracket, a funnel carried by the bracket, and means detachably connecting the funnel and bracket constructed and arranged to prevent movement of the funnel in the bracket.

4. In rayon spinning apparatus, a reciprocable support, a. funnel bracket pivoted thereto for movement from a substantially vertical inoperative position to a substantially hul-boum operative position, a. spring latch maintaining said bracket in its operative position and mleable by application of upward pressure on the bracket, a funnel carried by the bracket, and a quick detachable positive connection between the tunnel and bracket.
